Aradial RADIUS Server is a high performance RADIUS server with Tier 1 levels of reliability and scalability. It supports the latest RFCs, vendor specific attributes, and NAS templates, and has a multitude of pre-configured settings that support most access servers on the market today. It is based on a plugin architecture, which allows customization of the authentication and accounting logic outside of the core product. It is integrated with top billing solutions for ISP, WISP, Wifi, Hotspots, and VoIP.
Aranha is an application that uses an XML-RPC layer to retrieve information from one or more servers. The type of information gathered is implemented via plugins, and can be displayed or archived in several different ways. The data is gathered in Round Robin Databases (integrated with rrdtool) and can be accessed using a XUL interface available from the system. Plugins are very easy to write.
The Argus Open Project is focused on developing network activity audit strategies that can do real work for the network architect, administrator and network user. Argus is a fixed-model Real Time Flow Monitor designed to track and report on the status and performance of all network transactions seen in a data network traffic stream. It provides a common data format for reporting flow metrics such as connectivity, capacity, demand, loss, delay, and jitter on a per transaction basis.
Argus is a system and network monitoring application. It will monitor nearly anything you ask it to monitor (TCP + UDP applications, IP connectivity, SNMP OIDS, etc). It presents a clean, easy-to-view Web interface. It can send alerts numerous ways (such as via pager) and can automatically escalate if someone falls asleep.
Arno's IPTABLES Firewall Script is a secure stateful firewall for both single and multi-homed machines. It supports NAT and SNAT, port forwarding, ADSL ethernet modems with both static and dynamically assigned IPs, MAC address filtering, stealth port scan detection, DMZ support, protection against SYN/ICMP flooding, experimental IPv6 support, multi-interface/aliased-IP support, and extensive user definable logging with rate limiting to prevent log flooding. It has plugin support to add extra features (like SSH Brute Force protection and (Racoon) IPSEC support). It is easy to configure and highly customizable. A filter script that makes your firewall log more readable is also included.
This is a Linux driver for the Artec AS6E scanner. It scans on all available hardware resolutions in color, greyscale, and lineart, and functions in EPP, PS/2, and SPP parallel port modes. It can be used as a stand-alone program from the command line, or through the SANE (Scanner Access Now Easy) project's software.
AsItHappens is a real-time network statistics collector and grapher. It collects data from devices over a network via ICMP and SNMP and displays them on a graph, optionally storing collected data in a database for later retrieval. Collection types include network response, bandwidth usage, processor usage, memory usage, Cisco NBAR, and Cisco NetFlow. AsItHappens polls data in regular intervals, which can be in the order of milliseconds, to give immediate feedback on network performance, and it can also graph flow information from packet capture files. AsItHappens includes the Self Defending Network, a horizontal shoot-em-up based on collected graph data.
